Enuratique

Originally I used the “Countdown Timer” plugin written by Andrew Ferguson to accomplish what I wanted, 
however, his implementation to output in just days also outputted extraneous text that I was 
not interested in. On top of that, the actual count algorithm was flawed. Rather than hack 
this plugin to pieces to get the output I needed, I decided to just roll my own.
This is a bare bones, no-frills plugin since this is my first attempt at it. This means no 
fancy options or configuration screens.
To use the plugin, simply install it and then use the following shortcode to output the number 
of days until a given date in its place:
[days_until date=”SPECIFIC DATE”]
Where “SPECIFIC DATE” can be any text that that PHP’s strtotime function can understand.

Days Until

Outputs the number of days until a specified date from shortcode embedded in content.

This utility plugin adds a series of css classes that allow easy addition of set padding and margin to any element.
For basic use, the classes follow the format of [margin / padding][location letter: all, top, right, bottom, left, vertical, horizontal][amount: none, small, medium, large, extra large (0.5em, 1em, 2em, 4em)]
Also in the basic classes are percentages, taking the place of the last letter in the format [p][percentage] e.g. p7-5 for 7.5% or p15 for 15%.
Examples of Basic Classes:
<ul>
<li>man > margin all none = margin: 0px;</li>
<li>prl > padding right large = padding-right: 2em;</li>
<li>mvp5 > margin vertical 5% = margin: 5% 0;</li>
</ul>
Additional utility classes – First / Last child, Child / Sub
To add selective classes for adding margin / padding to the first / last child, any child, or any sub-element of the required element, simply add ‘last-‘, ‘first-‘, ‘child-‘, or ‘sub-‘ to the beginning of the basic classes.
Examples of Child Classes
<ul>
<li>last-mhxl > last-child margin horizontal extra large = last-mhxl :last-child { margin: 0 4em; }</li>
<li>last-pbn > last-child padding bottom none = last-pbn :last-child { padding-bottom: 0; }</li>
<li>first-mtm > first-child margin top medium = first-mtm :first-child { margin-top: 2em; }</li>
<li>child-mal > child margin all large = child-mal > * { margin: 4em; }</li>
<li>sub-php5 > sub elements padding horizontal 5 percent = sub-php5 * { padding: 0 5%; }</li>
</ul>
Additional utility classes – Responsive margin / padding
You can also apply the margin / padding required to certain screen widths, ranging from xl (min: 1200px) to xs (max: 480px). To use these responsive classes, add -[screen-size] to the end of the basic classes.
Examples of Responsive Classes
<ul>
<li>mrm-lg > margin right medium, large screen = (max-width: 1199px) and (min-width: 980px) margin-right: 2em;</li>
<li>pas-xs > padding all small, xsmall screen = (max-width: 480px) padding: 0.5em;</li>
<li>mhp15-md > margin horizontal 15%, medium screen = (max-width: 979px) and (min-width: 768px) margin-left: 15%; margin-right: 15%;</li>
</ul>
